Hi,i noticed after i watered the other day that there is yellow patches developing on a couple of the middle to to top leaves...

It is a moby dick auto at 23 days old.
Wesltands with added ji and perlite
Temps indoors about 22c and been taking it outside when the sun is out.
Only have it under 1 46w cfl indoors.
Been watering with high ph tap water like 7.6 and the run off is coming off at like 6.2 or thereabouts (ph strips),havnt fed it any nutes at all,will be getting some 2moro but not sure what yet.
Could anyone shed some light as to what the patches are and why its doing that ? and what sort of nutes i need,its starting to preflower like crazy... This is my 1st grow like an experiment and am enjoying learning lots about it.
